Zinc Bromate, Zn(BrO3)2

Crystals of the hexahydrate Zn(BrO3)2.6H2O, efflorescent in vacuo, are obtained by evaporating a solution of zinc oxide in bromic acid. Deliquescent, unstable crystals of Zn(BrO3)2. 3H2O.2NH4 were obtained by adding ammonia to a solution of the salt. Zinc bromate is soluble in its own weight of water at 15° C., and its density is 2.506.

The crystals, formed by slow cooling or evaporation, are mostly octahedral in habit.
